RRFC touch starts by generating an AC voltage which is applied to two adjacent corners and a DC voltage which is applied to the opposite two corners forming a voltage ramp across the sensor and a corresponding ramped electro-static field. The controller repeats this for all four possible corner combinations.. The measurement of the energy in the fields happens at each corner in a way that efficiently removes all capacitance effects except those that are related to a finger touch. In its simplest form, the actual touch point on the X or Y axis is a ratio of the measured results from the two ramped fields that were generated on that axis.

Not so surprisngly, they seems to plan to be a solution provider of dual-mode pen and touch technolgoy. At this time, N-trig and InPlay technologies are major providers of dual-mode pen and touch technolcoy.
